For a four corner device, can four SEN-14729 5 KG straight bar load cells be attached together, in parallel, to the “Load Cell” interface connector (JP3 or JP11 ) of the SEN-13261 Load cell interface board?
Sadly no, not easily.
You could use four 3 wire load sensors with the OpenScale but not four 4 wire load cells.
If you wanted multiple 4 wire load cells, you need a summing box to combine them.
